YouTube takes an upload of up to 256 GB or 12 hours, whichever is less.

Twitch recommends 6,000 kbps for 1080p at 60 fps, and 4,500 for 1080p at 30 fps or 720p at 60.

YouTube Live recommends 17,000 kbps for 1080p at 60 fps with H.264, and 14,000 at 30 fps.

In OBS, a Recording Quality of "Same as stream" records at the stream's quality, so the recording's size follows the stream's bitrate.

Exporting the edit for YouTube: it recommends 8 Mbps for 1080p at 24 to 30 fps, and 12 Mbps at 48 to 60 fps.
